The problem is, i use Compiz a lot, specially the tool to change desktops with the mouse scroll wheel. But when I had Ubuntu installed, I could change it just by scrolling the wheel up or down when the mouse pointer was over the background. It dind't work when the mouse pointer was over some window, Open Office for instance, wich I also use a lot.Now, even if I set the configurations to activate the wheel, it changes desktop, no matter where the pointer is, wich makes the tool useless.Now I have to set the tool to work when I scroll the wheel as I am pressing some key. It doesn't make the tool worthless, but it is really not the same thing. It slows me down too much! Its annoying.

Thank you guys, but i already have Desktop Cube plus Rotate Cube both enabled.My problem is not to rotate the cube, but how to use the mouse wheel to rotate it.I set it to work when I press ctrl and alt as I scroll it up or down.I can also set to work without pressing the keys, but then it will rotate the cube everytime.Imagine I am on firefox trying to scrool down the page, for example.The cube rotates even if the mouse pointer is over the browser window. It doesn't scroll the page down.

As I remember, in Ubuntu I could set it to rotate the cube only with the mouse wheel, but it would only work with the mouse pointer over the background.

Sorry if muy english is not that good, but it's the best I can do to explain it.

Maybe there's nothing to do, but I just can't understand why it worked that way in Ubuntu.

hmmmmm....interesting...so the mouse is viewing the screen (whether a window is open or not) as if there is nothing there. Will do some research for you.......real quick though...have you done all of the mint updates, etc.?

All updates are ok, except for xorg-driver-fglrx (level 4) and hal-info (level 5).Besides, there are a bunch of updates from Synaptic (kernel, for example) wich I don't install until Mint has it tested.

Stay clear of Levels 4 and 5 updates unless you are experiencing some sort of compatibility issues and you are at the end of your rope. Whatever you do, back up your existing installation before you attempt something -- anything at all -- that are likely to bring about unexpected behavior.

I've spent some time exploring this and all I can find is that it should not do what it does I have only looked for solutions for Compiz - maybe this is a wider problemI think it's time we find out about your hardware - big difference between ATI, nvidia and Intel...
